Peeking into occluded joints: A novel framework for crowd pose estimation(ECCV2020)

Dependencies

PyTorch(>=0.4 && <=1.1)
mmcv
OpenCV
visdom
pycocotools

This code is tested under Ubuntu 18.04, CUDA 10.1, cuDNN 7.1 environment with two NVIDIA 1080Ti GPUs.

Python 3.6.5 version is used for development.

OCPose

About OCPose

We build a new dataset, called Occluded Pose(OCPose), that includes more heavy occlusions to evaluate the MPPE. It contains challenging invisible jointsand complex intertwined human poses.

Dataset	Total	IoU>0.3	IoU>0.5	IoU>0.75	Avg IoU
CrowdPose	20000	8704(44%)	2909(15%)	309(2%)	0.27

Pretrain module

Here, we employ top-down module(Alphapose+ based on pytorch) as our initial module.
The pretrain checkpoints trained by official codes could be download as following:
SPPE
yolov3

Training

Instead of using pretrain module in coco2017, we simply provide you quick-start version, where you merely train the OPEC-Net from processed data including both coco and CrowdPose.

Before training, the structure of projects like:

coco

|      xxxxx.jpg   
crowdpose
|   images
|      xxxxx.jpg

Training script

e.g.

TRAIN_BATCH_SIZE=14
CONFIG_FILES=./configs/OPEC_GCN_GrowdPose_Test_FC.py
bash train.sh ${TRAIN_BATCH_SIZE} ${CONFIG_FILES}

after training, the result of CrowdPose is save into checkpoints/name/mAP.txt
the format of results like:

epoch (without best match) (use best match)

Test script

e.g.

CHECKPOINTS_DIRS='path to your checkpoints files'
CONFIG_FILES =./configs/OPEC_GCN_GrowdPose_Test_FC.py
bash test.sh ${CHECKPOINTS_DIRS} ${CONFIG_FILES}
